## Introduction

Kunpeng Zlib Acceleration Engine is used to build performance competitiveness of common software libraries on the Kunpeng platform.

As a new function in the HiSilicon Kunpeng 920 processors, Kunpeng Zlib Acceleration Engine provides a hardware-enabled foundation for  compression. It significantly increases the performance across cloud, big data, and storage applications and  platforms.  By using  Kunpeng Zlib Acceleration Engine, you can:

- Have higher-performance compression and decompression
- Maximize CPU utilization

The compression and decompression algorithm supported by Kunpeng Acceleration Engine are:  gzip/zlib

## Installation Instructions

Clone the Github repository containing the Kunpeng Accelerator Engine Driver.

```
git clone https://github.com/kunpengcompute/KAEzip
```

Download the release version of Kunpeng Accelerator Engine Driver from:

<https://github.com/kunpengcompute/KAEdriver/releases>

Firstly, build and install the accelerator driver.
Note: To build the Kunpeng Accelerator Engine Driver, install the `kernel-devel` package first.

```
tar -zxf Kunpeng_KAE_driver.tar.gz
cd kae_driver
make
make install
modprobe uacce
modprobe hisi_qm
modprobe hisi_zip
```

Secondly, install the accelerator library:

```
cd warpdrive
sh autogen.sh 
./configure 
make 
make install
```

Then Install KAEzip library:

Download [zlib-1.2.11.tar.gz](https://www.zlib.net/zlib-1.2.11.tar.gz) at KAEzip/open_source.

```
cd KAEzip
sh setup.sh install
```
